Description

Technical Field

[0001] The utility model relates to the technical field of high voltage electricity, in particular to a protective composite insulator component. Background Art

[0002] The field of high-voltage electrical technology covers power systems and transmission technology, high-voltage insulation technology, high-voltage electrical equipment and relay protection, high-voltage insulation diagnosis and testing technology, high-voltage power electronics technology, and high-voltage experiments and research. The development of high-voltage electrical technology is of great significance to improving the reliability of power systems, promoting energy efficiency, promoting industrial development, and promoting social and economic growth.

[0003] Protective composite insulator assemblies are widely used in the field of high-voltage electrical technology because they provide excellent insulation performance and reliability in high-voltage environments. Compared with traditional ceramic insulators, protective composite insulator assemblies have better mechanical strength, vibration resistance and impact resistance through the structural design of composite material outer layer and metal component support. At the same time, this insulator assembly is light in weight, which helps to reduce the load on transmission lines and simplify equipment installation.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Common composite insulator assemblies lack protective devices specially designed to drive away birds, which easily lead to problems such as bird nesting, carrying metal objects and bird droppings, thereby causing damage, pollution and corrosion to the surface of the insulator, reducing the performance and reliability of the insulator; 2. Currently common composite insulator assemblies usually do not have seismic buffering functions. Composite insulators cannot effectively buffer when facing external vibrations and impact loads, which easily leads to the breakage of the insulators, and the connections are prone to wear due to vibrations, temperature changes and power loads, resulting in failure, loosening or falling off of the connection parts. Utility Model Content

[0005] The purpose of the utility model is to provide a protective composite insulator assembly to solve the problem of lack of protective devices specially designed for driving away birds and lack of anti-seismic buffering function proposed in the above background technology. To achieve the above purpose, the utility model provides the following technical solutions: a protective composite insulator assembly, comprising an insulator body, a buffer washer is installed on the top of the insulator body, a fixing ring is installed on the top of the buffer washer, a plurality of fixed shafts are installed on the outer surface of the fixing ring, a mounting frame is installed on the side of the fixing shaft away from the fixing ring, a plurality of support rods are installed on the bottom of the mounting frame, a plurality of rotating sleeves are rotatably connected to the surface of the support rod, a plurality of connecting rods are installed on the outer surface of the rotating sleeve, a mounting cover is installed on the side of the connecting rod away from the rotating sleeve, a reflector is movably installed inside the mounting cover, a mounting seat movably installed with the buffer washer is provided on the top of the fixing ring, a plurality of limit bayonet holes are installed on the top of the inner wall of the mounting seat, a buffer spring is installed inside the limit bayonet hole, and a buffer seat is installed on the side of the buffer spring away from the limit bayonet hole.

[0006] Further preferably, the connecting rod forms a rotating structure with the supporting rod through a rotating sleeve.

[0007] Further preferably, the buffer seat and the buffer spring form a buffer structure.

[0008] Further preferably, the support rods are symmetrically distributed about a horizontal center line of the mounting frame.

[0009] Further preferably, the rotating sleeves are evenly and equidistantly distributed on the surface of the support rod.

[0010] Further preferably, the fixed axes are distributed equidistantly in a ring shape with the central axis of the fixed ring as the origin.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the connecting rod can drive the mounting cover and the reflector to rotate under the action of wind, so that the mounting cover and the reflector can continuously change their positions and angles, generate dynamic reflections or noise, and have a deterrent effect on birds. It can effectively prevent birds from nesting and metal objects from attaching, reduce pollution and corrosion on the surface of insulators, thereby protecting the surface of insulators and extending their service life, while reducing maintenance costs and work risks, and improving the reliability and safety of power equipment.

[0013] In the utility model, the balanced distribution of insulators on the fixed axis can avoid instability caused by uneven force, and the annular equidistant distribution can share the load of the insulator assembly, so that the load is evenly transmitted, thereby improving the overall reliability and stability, and having a seismic buffering function, which effectively mitigates the impact of external vibration and impact loads on the insulators, reduces the risk of breakage, and reduces the possibility of failure, loosening or falling off of the connecting parts.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 The utility model provides a technical solution: a protective composite insulator assembly, including an insulator body 1, a buffer washer 2 is installed on the top of the insulator body 1, a fixing ring 3 is installed on the top of the buffer washer 2, a plurality of fixed shafts 4 are installed on the outer surface of the fixing ring 3, a mounting frame 5 is installed on the side of the fixing shaft 4 away from the fixing ring 3, a plurality of support rods 6 are installed on the bottom of the mounting frame 5, a plurality of rotating sleeves 7 are rotatably connected to the surface of the support rod 6, a plurality of connecting rods 8 are installed on the outer surface of the rotating sleeve 7, a mounting cover 9 is installed on the side of the connecting rod 8 away from the rotating sleeve 7, a reflector 10 is movably installed inside the mounting cover 9, a mounting seat 11 movably installed with the buffer washer 2 is provided on the top of the fixing ring 3, a plurality of limiting bayonet holes 12 are installed on the top of the inner wall of the mounting seat 11, a buffer spring 13 is installed inside the limiting bayonet hole 12, and a buffer seat 14 is installed on the side of the buffer spring 13 away from the limiting bayonet hole 12.

[0020] In this embodiment, Figure 2 As shown, the connecting rod 8 forms a rotating structure with the supporting rod 6 through the rotating sleeve 7; the connecting rod 8 can drive the mounting cover 9 and the reflector 10 to rotate under the action of wind, so that the mounting cover 9 and the reflector 10 constantly change their positions and angles, generate dynamic reflections or noise, and have a deterrent effect on birds.

[0021] In this embodiment, Figure 3 As shown, the buffer seat 14 and the buffer spring 13 form a buffer structure; the design of the buffer structure protects the insulator from external vibration and impact, ensuring the safety and reliability of power transmission.

[0022] In this embodiment, Figure 2 As shown, the support rods 6 are symmetrically distributed about the horizontal center line of the mounting frame 5, which ensures the stable operation of the bird-repelling device and effectively drives away the birds. The symmetrical layout of the support rods 6 evenly distributes the weight and force, so that the structure can remain stable under the action of wind.

[0023] In this embodiment, Figure 2 As shown, the rotating sleeves 7 are evenly and equidistantly distributed on the surface of the support rod 6, ensuring that the bird-repelling device is fully distributed on the support rod 6, covering a wider range. The equidistant distribution increases the mobility and rotation of the bird-repelling device, effectively driving away birds.

[0024] In this embodiment, Figure 2 As shown, the fixed shaft 4 is equidistantly distributed in a ring shape with the central axis of the fixed ring 3 as the origin; the balanced distribution of the insulators on the fixed shaft 4 is ensured, and the instability caused by uneven force can be avoided. The equidistant distribution in the ring shape can share the load of the insulator assembly, so that the load is evenly transmitted, and the overall reliability and stability are improved.

[0025] The use method and advantages of the utility model: When the protective composite insulator assembly is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 and Figure 3As shown, after the protectable composite insulator assembly of the present invention is installed in an outdoor circuit system, because the installation position of the insulator is often selected in a high and open outdoor environment, the power of wind is used to drive the rotating sleeve 7 and the reflector 10 to rotate, so that the installation cover 9 and the reflector 10 constantly change their positions and angles, generate dynamic reflections or noise, and have a deterrent effect on birds. In addition, in daily outdoor circuit systems, they are often affected by external environmental factors such as vibration and impact, which leads to the insulator being easily damaged and the insulation performance being reduced. Therefore, under the joint action of the buffer spring 13 and the buffer seat 14, it can effectively buffer the external vibration and impact load, avoid the problem of easy damage to the insulator, and avoid wear of the connection caused by factors such as vibration, temperature change and power load, and eliminate the problem of failure, loosening or falling off of the connection parts.
